Inhalt:
In this paper, we present an ultra-broadband on-chip spectrometer utilizing only a few dispersion-engineered micro-ring resonators, achieving a > 325nm operational bandwidth with a < 20 pm resolution. This, to the best of our knowledge, sets a new record in operational bandwidth for on-chip spectrometers.
